Answer:
Volume of sphere = 44.57 cm³
Step-by-step explanation:
Given:
Diameter of sphere = 4.4 centimeter
Value of π = 3.14
Find:
Volume of sphere
Computation:
Radius of sphere = Diameter of sphere / 2
Radius of sphere = 4.4 / 2
Radius of sphere = 2.2 centimeter
Volume of sphere = [4/3][π][r³]
Volume of sphere = [4/3][3.14][2.2³]
Volume of sphere = [4/3][3.14][10.648]
Volume of sphere = [1.333][3.14][10.648]
Volume of sphere = 44.568
Volume of sphere = 44.57 cm³
11:27
First, 1:25 to 1:00 would be 25 minutes early. Therefore, you do 52 - 25 = 33. One hour and 33 minutes early now. Then, you do one hour before 1:00 which would be 12:00. Finally, you would do 60 - 33 because 12:00 is technically 12:60. 60 - 33 = 27. The answer is 11:27.
The quadratic equation is in factored form, which is f(x) = (x - a)(x - b), where a and b are the x-values for the x-intercepts.
The x-values for the x-intercepts are 4 and -2. We know that the y-value at any x-intercept must be 0 (otherwise it isn't an x-intercept).
Thus, either the points (4,0) or (-2,0) must be your answer (the question is only asking for one x-intercept).
Answer:
pretty sure it's A. (4, -4)
An equation is formed of two equal expressions. The given equation is not true.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The complete question is: Check whether the given equation is true or not?cos2pi/7+cos4pi/7+cos8pi/7=1/8.
To know if the given equation, 
is true or not, both the sides of the equation are needed to be solved separately.
The value of 
when simplified is equal to -0.5, or the value can be written as -(1/2).
Since the right side of the equation is equal to -1/2, while the right side of the equation is 1/8. Thus, the given equation is not true.
Hence, the given equation is not true.
